The color of flame retardant fabrics will fade after a period of time.What's the reason that cause the color fade?It's a complex process.

To improve and optimize the performance of dyestuff is an important way to minimize the color fade of protective fabric and clothing.

If there are a lot of -NH2 or -OH in the dyestuff molecular structure,it will easily have oxidation reaction,thus decrease the fastness to light.When there are -COOH,-SO3H,-NO2 in the dyestuff molecular,it will increase the color fastness of dyestuff.

Besides,color fade also has relations with molecular structure.Weak stability,active reaction ability -H atom will promote the oxidation process.

In a word,the reason of color fade of dyed clothing is the dyestuff appetency to molecule,spectral property,concentration of dyestuff and chemical structure,etc.So, the main reason of color fade for dyed clothing is the dyestuff.
